' between the fuel tank and the vaporizing tube. i

It is a further object of the invention to provide a simple andeiicientstructure comprising a connectionfrom the fuel container to thevaporizing tube which permits' ready removal of the vaporizing tu e andwhich comprises a positionin means for the vaporizing tube so that t econnection to the fuel tank can readily be made. r

It is more specifically an object of the invention to provide a simpleandefcient structure comprising a vaporizing tube, abracket 4 carried bythe frame of the stove through which the tube passes and from which itisv readily removable, said bracket and tube havinginter-engaging meansfor positioning the tu e, said tube having an opening therein and aconduit extendin from the fuel tank to said bracket adapte to-engage thetube and be connected thereto when the tube is so positioned, means alsopreferably being provided for holding the tube firmly in position.

These and other objects and advantages of ,the invention will be fullyset forth in the following description made in connection with theaccompanying drawings, in which like reference lcharacters refer tosimilar parts throughout the several views, and in which Fig. 1 is a topplan view of a portion of a stove showing the invention applied thereto;

Fig. 2 is for the vmost part a horizontal section through the vaprizingtube and supporting bracket and connection to the fuel tank, a portionof the latter being shown in' plan;

Referring to the drawings, a portion of a stove adaptedto -burnhydro-carbon fuel is shown, comprising a substantially rectangular frameformed of vertically disposed sheets of metal l0, the same bein' shownas connected by suitable angles 11. top plate l2 is provided, wardlyturned nge at its 'edge and the same havin openings 12a, therethrough,said top plate belng secured to the frame by screws 13."A burner 14 isshown as disposed centrally beneath the opening 12a and a'portion of amixing chamber 15 is shown which communicates with and supplies acombustible mixture lto burner 14. A fuel tank 16 is disposed at one endof the frame 10 and is secured thereto vby suitable strips 17 extendingabout said tank and being secured to the outer end of frame 10 by anysuitable `means. A vaporizing tube 18 is provided n having at its innerend a slightly reduced portion 18a. which is received in an opening inthe -end of mixing chamber 15, a shoulder gaged by the valve formingportion-19b of l l the valve stem 19. Stem 19 has an externallongitudinal-extending slot 19e through the threaded ,portion thereof sothat gas may pass through tube 18 and around ysaid stem. The outer endof valve stem 19 has an annular member 21 secured thereto, the inner endof which is arranged to abut a shoulder on the inner wall o f tube 18..-A packing cap 22 is threaded onto the outer end'of tube 18 and adaptedto compress packing material 23 bel.

eferably having a down-'I tween the end thereof and the end of tube 18about the member 21 thus packing said valve stem 19. Valve stem 19 atits extreme outer end has secured thereto an operating hand wheel 24held in lace by a nut 25 threaded on the end of sai stem. Vaporizingtube 18 also has a tapered aperture 18e at one side thereof and thebeveled or tapered end of a coupling plug 26 is ada ted to engage insaid aperture so as to ti ht y connect with said tube. The outer en ofplu 26 has secured therein the end ofa tube 2 which extends laterallyand 'is connected at its other end by a coupling sleeve 28 to a conduit29 which is communication with a fuel tank 16. Member 26 is threadedinto one side of a bracket 30, said bracket having an inner cylindricalportion supported upon the spaced leg's 30a having feet or lugs 30b withiiat sides engaging the inner side of the end member of frame 10.Bracket 30 is secured to said end member by the headed and nutted bolts31, the same being shown as provided with springl locking washers. A setscrew 32 having a blunt inner end is threaded into the cylindricalportion of bracket 30 opposite the plug 26. Bracket 30 has an oblongaperture 30e extending centrally therethrough, tube 18 passing throughsaid aperture. Said bracket also has formed lto on its inner sidebetweenY legs 30a a recess 30d of general rectangular form.' Tube 18 hassecured thereto an angular lu 33, one endA of which projects laterallyan is ada ted to seat in the recess 30d as shown in igs. 2 and 4.

In assembling the parts the bracket 30 is secured in position on the endof frame mem'- ber 10, tube 18 is then passed through opening 30e in thebracket, the portion 18a entering the mixing chamber 15 and the tube canbe turned by wheel 24 until lug 33 seats in the recess 30d. When saidlug is thus seated in the recess the opening 18e is l1n proper positionto receive the end of plug 26. Screw 32 will be turned to engage tube 18ai'nd plugf26 can then be tightly screwed against said tube and into theopenlng 18e thus efficiently connecting tube 27 to the tube 18. Theparts are now in firm and secure position and the stove can be operatedand .fuel admitted to the burner by turning hand wheel 24. The presentstructure has resulted in quite a few advantages. A much simplervaporizing tube is obtained and one which can be quickly removed byloosening screw 32. With the previous constructions it was necessary tohave a coupling member connected to the outer end of tube 18 and betweenthe tube and hand wheel 24. It is often desired to remove the vaporizingtube to clean the same. With the present structure it is only necessaryto screw olf the packing sleeve 22 after which the stem 19 can beremoved and the tube and stem thoroughly cleaned. The tube is easilyreplaced and is quickly brought to proper position by the 1,sss,aoo

seating of lug 33 in the recess 30d. The structure is thus easily andquickly manipulated and can be properly assembled b anyone, whether theyhave any knowle ge of mechanism or not. The device has been amplydemonstrated in actpal practice and found to be very successful andeiicient.

It will, of course, be understood that various changes may be made inthe form, details, proportions and arrangement of the parts, withoutdepartin from the scope of applicants invention, whlch, generallystated, consists in a device capable of carrying out the objects aboveset forth, in the novel parts and combinations of parts disclosed anddelined in the appended claims.
